ILLINOIS, .A CORPORATION OF ILLINOIS CUTTER BAB Application filed September 6, 1929. Serial No. 390,688.

On the drawing Figure l is a top view of the cutter bar assembly and Figure 2 is a sectional view on line 2-2 J of Figure l.

The guard nger l shown in dotted lines in Figure 2, is of a type commonly used and is generally cast in groups of two or more which are secured in place on the front 1o frame bar 2 of a harvester by bolts 3, the same bolts being utilized to attach the ger bar to the front frame bar 2. From this structure it is evident that if it is desired to cutcloser to the ground because of the nature of a particular crop, such as soy beans, a diiferent cutting mechanism structure must be employed and to that end I have provided a supplemental device to be attached to the frame bar 2, after the guard fingers have been detached by loosening and removing the bolts 3.

The frame bar 2 is made of steel L bar and on the vertical leg Z) thereof the cutting mechanism is mounted, utilizing the same bolts 3 to secure either type of device shown. The cutting mechanism, shown in full lines in the drawing, includes a linger bar 4 made of steel L bar and of smaller dimensions than the bar 2, the vertical leg of the finger bar 4 80 being secured to the vertical leg of the bar 2 by the bolts 8. The horizontal leg 5 of the nger bar 4 extends forwardly and is a sufficient distance above the plane of the horizontal leg 0 of the bar 2 so that the bottom of the guard finger 6 is in said plane so as to move over the stubble without gathering soil or dbris of the harvest. The rear end of the guard linger 6 is flat and firmly in contact with the vertical leg 2') of the bar 2 to add to the rigidity of the structure.

rlhe guard fingers 6 are secured to the under side of the horizontal leg 5 of the bar 4 by bolts 7 and operating in the guard fingers in the usual manner is the knife bar 8 carrying cutting sections 9 which cooperate with ledger plates 10 to sever the plants being harvested. Keeper plates ll are secured on the upper side of the leg 5, of the bar 4 by the bolts 7 and, as commonly used, hold the 50 knife bar in proper relation to the ledger plates. The bar 4, guard lingers 6 and the keepers ll are assembled and supplied as a complete unit and when mounted on the bar 2, the knife bar carrying the sections 9, is readily inserted at one end of the assembled unit, using the same knife bar that operated in the guard ngers l.

My device has proven very effective in harvesting crops where it is desirable to cut close to the ground and the change from one cutting device to the other can be quickly and readily made with considerable saving of time and labor.

What I claim isl. The combination of an L bar forming the front frame bar of a harvester, a leg of said bar disposed vertically, and a bottom leglextending rearwardly, asupplemental similar L bar having its vertical leg secured to the vertical leg of the first mentioned bar 7c and having 'a horizontal leg extending forwardly, guardiingers mounted on said forwardly extending leg and having their lower side in the horizont-al plane of the rearwardly extending leg of the first mentioned bar, and means to secure said bars together.

2. The combination of an L bar forming the front frame bar of a harvester, a leg of said bar disposed vertically, and a bottom leg extending rearwardly for attachment to a harvester frame, a supplemental similar L bar .having its vertical leg secured to the vertical leg of the iirstmentioned bar, and a horizontal leg extending forwardly above the plane of the horizontal leg of the iirst mentioned bar, guard ngers mounted on the horizontal leg of the supplemental bar and having their under side in the horizontal plane of the lower side of the horizontal leg of the lirst mentioned bar, and means to secure said bars together.

3. The combination of an L bar forming the front frame bar of a harvester, a leg of said bar disposed vertically, and a bottom e5 leg extending rearwardly, a supplemental similar L bar having its vertical leg secured to the vertical leg of the first mentioned bar and having a horizontal leg extending forwardly, and guard fingers mounted on the forwardly extending leg, and means to secure said bars together.

4. The combination of an L bar forming the front frame bar of a harvester, a leg of said bar disposed vertically, and a bottom leg extending rearwardly, a supplemental similar L bar having its vertical leg secured to the vertical leg of the first mentioned bar and having a forwardly extending horizontal leg, guard fingers mounted on the forwardly extending leg and having their rear ends flattened and in Contact with the forward face of the frame bar, and means to secure the finger bar to the frame bar.
